'ROTATABLE SEESAW.

Application filed July 8, 1922'. Serial No. 573,553.

To all whom it may concern:

Be it known that we, RUssELL C. FrnLns and ELMER F. FIELDS, citizens ofthe United States, residing at Pipestone, in the county of Pipestone and State of Minnesota, have invented certain new and useful Improvements in Rotatable Seesaws, of which the following is a specification.

Our invention relates to rotatable seesaws, and an object is to provide a device of this character having a see-saw board which can be caused to rotate as well as swing up and down and which can be used with 'safety by children without liability of getting their fingers pinched. Another object is to provide a device of this charac- ,ter which can be readily assembled and taken apart so as to be convenient for transportation.

The full objects and advantages of our invention will appear in connection with the detailed description, and the novel features embodied in our inventive idea will be particularly pointed out in the claims.

In the accompanying drawings, Fig. l is a top plan view of our device. Fig. 2 is a side elevational view thereof. Fig. 3 is a View in vertical section on the line 33' of Fig. 5. Fig. l is a view in verticalsection on the line 4-ei of Fig. 3.v Fig. 5 is a view in vertical section on the line 5-5 of Fig. 1.

As shown in the drawings, the casting 10 is supported by legs 12 and the upper surface of this casting is provided with a cy-' lindrical projection 14 which is received in a corresponding recess in the lower surface of a second or upper casting 16. A bolt 18 holds the two castings togetherso that the upper casting 16 may be rotated- Secured by upon the lower casting 1O; screws 20 to the upper side of the casting .16 is a horizontal cylindrical member 22 which oscillatingly receives a rod 24 which is held in place by a pin 26 secured-to the rod and working in an arcuate slot 28 in the upper half of the cylindrical member. A see-saw board of the desired length is secured to the rod 24: by screws 32. As

shown in Fig. 5, the lower surface of the board 30 is cut out to receive the upper portion of the cylindrical bearing member 22;

As will appear from Figs. 4 and 5, thequpper portion of the member 22 is reduced in length whereby it is not necessary to cut as long a groove in the board as would otherwise be the case.

The operation and advantages of our invention will now be obvious. The board 30. will ordinarily be of such length that its ends will hit the ground before the board castings having a cooperating projectionand recess to constitute a bearing for such.

movement, a horizontal cylindrical member secured to the upper side of said second casting, a rod mounted for oscillating in said cylindrlcal member, and a see-saw board secured to said rod. 3

2. A rotatable see-saw comprising a sup- 7 1 port, a casting mounted on said support, a second, casting mounted for rotation in a horizontal plane upon said first casting,said first casting having a cylindrical projection in its uppersurface fitting a recess in the lower side of said second casting, a horizontal cylindrical member secured to the upper side of said second casting, a rod mo-unted for oscillation in said cylindrical member, a pin secured to said rod and working in a-slot in said cylindrical member, and a see-saw board secured to said rod.

In testimony whereof we hereunto afiix our signatures. 7
